AS 5900E AMS1424 and AMS1428 Standard Test Method for Aerodynamic Acceptance of Aircraft De-icer, Anti-Icing Fluids

EUROLAB laboratory provides testing and compliance services within the scope of AS 5900E standard. This SAE Aerospace Standard (AS) specifies aerodynamic flow requirements and test procedures for AMS1424 Type I and AMS1428 Type II, III, and IV fluids used to defrost or prevent aircraft.

AS 5900E AMS1424 and AMS1428 Standard Test Method for Aerodynamic Acceptance of Aircraft De-icer, Anti-Icing Fluids

The purpose of this standard is to provide acceptable aerodynamic properties of de-icing-anti-icing fluids as they flow from aircraft lift and control surfaces during take-off ground acceleration and climb. The aerodynamic acceptance of an airplane ground de-icing-anti-icing fluid is based on the boundary layer displacement thickness (BLDT) of the fluid on a flat plate, measured after experiencing a free-flow velocity time history of a representative airplane take-off.

The acceptability of the fluid is determined by comparing the BLDT measurements of the candidate fluid with a data generated from a reference fluid BLDT and BLDT values ​​on a dry (clean) test plate. The test is performed in the temperature range where the undiluted and diluted liquid will be used in airline service.
